I recently had the pleasure of being interviewed by a team from CNN on sustainability issues in the sushi industry.This clip is me explaining what I call the “4-S rule” – a simple, if somewhat crude, guide to eating in a more sustainable fashion at the sushi bar (oh, and a small correction to CNN’s byline – I am a co-founder of Tataki Sushi Bar, but I don’t actually own the restaurant.)
As I discuss in the video, there are four adjectives, each starting with the letter S, that form the eponymous rule.If a sushi bar patron bears these descriptors in mind while he or she orders, it can markedly diminish the environmental footprint created by dinner.This is not a perfect system – there are exceptions to each of the four “S” words – but by and large, it does help one to order a more sustainable sushi meal overall.
Skipjack tuna served nigiri-style with gobo, scallions, and a shiso leaf. The skipjack is the smallest tuna found in the sushi industry, and has both the lowest average mercury content and the highest reproduction rate.
The first word is SMALL.Smaller fish are generally lower on the trophic scale (food chain), grow more quickly, die younger, and breed in larger numbers.These biological survival tactics are employed by many fish to help them withstand heavy predation — they play the numbers game and simply create as many offspring as possible so a few manage to escape the yawning maws of hungry predators. In essence, these are the kind of fish that are designed to be fed upon.Their physiology and population dynamics are generally more resilient to our fishing pressure and protein demand than top-of-the-food-chain carnivores, such as large tunas, swordfish, and sharks.Moreover, smaller fish generally have less mercury accumulation in their systems than these apex predators due to their shorter life spans and less voracious appetites.
Wild coho salmon, sashimi-style. Alaskan coho is well managed, healthy for consumers, and seasonally available.
The next word is SEASONAL.Seasonality is key to sustainability.If we are to reduce our carbon dependency and rekindle our connection with the ocean, we need to be more aware of where we are and what time of year it is when we order our fish.A good rule of thumb is to order off the specials board rather than the laminated menu when possible – any items on a year-round menu are unlikely to be sourced on a basis of seasonal awareness.It was our demand that certain intrinsically seasonal products be available to us year-round that gave rise to environmental missteps like conventional salmon farming.This category also offers us the added opportunity to take advantage of seasonal vegetables and fruits, which innovative chefs often incorporate into their specials.
Pacific saury prepared over wood charcoal. These cold-water schooling forage fish have high levels of omega-3 fatty acids.
The third word is perhaps the most surprising – SILVER.Eat sushi that is served with a silver skin still on it.This category of fish is known as hikari mono in Japanese, and contains mackerels, halfbeaks, shads, and similar fish.These animals tend to be loaded with omega-3s as well as being low in mercury, and can be sourced from many well-managed fisheries.An added bonus is that the hikari mono are some of the most treasured fish in the repertoire of a traditional sushi chef; a menu featuring these items will often prove to be an unforgettable culinary experience. I highly encourage all sushi-goers to explore the world of hikari mono – you just may find your new “absolute ultimate all-time favorite” sushi item.
Kumomoto oysters on the half-shell with momoji oroshi. Oysters are high in protein and easy to raise in low-impact farms.
The final word is SHELLFISH, and I’m speaking specifically of bivalves and mollusks.Not only are these creatures excellent sources of protein, but they are considered by many to be delicacies and aphrodisiacs. Bivalve and mollusk aquaculture has sound environmental benefits as well: it tends to involve relatively low-impact farming methods when compared to other types of fish farming, such as tuna ranches or salmon farms.As filter-feeders, animals like clams, scallops, and oysters can be grown without the use of any additional feed. This reduces their dependence on marine resources and eliminates the kind of inefficient protein use that we find in operations like hamachiand unagiranches. These mollusks also grow quickly, and can be raised in cages and bags that require no dredging or other types of seabed alteration during harvest.
That’s about the size of it.Small, seasonal, silver, and shellfish – a quick-and-dirty road map to a more eco-groovy sushi experience.There are, as I mentioned earlier, numerous exceptions to this rule, but it serves as a fairly reliable lodestone for those who are interested in shifting their sushi dining habits toward a more sustainable paradigm.
Oh, and one final quip: as it happens, the letter S occurs exactly four times in the term “sustainable sushi.” Remember that to keep the 4-S rule in mind.
One of the little joys of the sushi dining experience is the rapport that one builds with the chef. Unique among major North American cuisines, sushi offers a customer the opportunity to dine in a face-to-face setting with those behind the sushi bar. In addition to watching the masterful knife-play that is involved with the proper preparation of one’s mixed sashimi plate or order of kohada nigiri, it affords us an all-too-uncommon experience in modern America: the chance to get to know the person who is feeding us.
Closed kitchen
Consider our other restaurant dining options. It is exceedingly rare to find oneself in a non-Japanese eating establishment wherein one has the choice to sit directly before the executive chef and interact with him (over 95% of sushi chefs in the United States are men… but that’s the subject of a different post) throughout the meal. Try to find a French restaurant where the chef prepares your coq au vin tableside, or a California fusion joint that seats you next to the line cook so you can chat while he sets you up with your steamed halibut with Napa cabbage and mango salsa.
Only in the sushi world are we treated to this intimate experience of dining in the company of the chef. The irony of this situation, however, is that even though sushi diners have the opportunity to connect with the architect of the dishes they enjoy, they are often more removed than ever from the real star of the show — the fish itself.
Sushi does not typically present itself to us as fish. When it arrives at the table, it has been artfully sliced and diced, festooned with ornamental seaweeds and vegetables, and cradled by softly interwoven granules of rice. It’s a magnificent creation: a delightful dining experience that enraptures the eyes as well as the taste buds… but at what cost? Is there a price to pay for perfection in presentation?
Possibly.
I've got a secret
The oceans are under threat from overfishing, pollution and trash dumping, bottom trawling, and more. One of the reasons that these practices are allowed to continue is that the realm of the aquatic is separated from our perception by our inability of human vision to pierce the waves. What lies beneath the ocean’s surface is nothing as much as a deep and fascinating mystery. If we could bear quotidian witness to the damage wrought by our actions, would we still behave this way?
No one here but us flowers
It is difficult for us to offer fish the respect they deserve when we are unable to perceive them as living, breathing animals that have unique characteristics and habits, that form an integral part of an ecosystem that we are only just beginning to comprehend. In the context of sushi, these fish — many of which have never been seen by the vast majority of Americans in any form other than sliced to ribbons — are not presented as animals, but rather as an assortment of delectable morsels in a culinary tapestry woven together for our sensual pleasure.
So how do we surmount this obstacle? Part of saving the oceans is building awareness of the impacts of our choices, so how can we enjoy sushi while maintaining a connection to the fish that gave its life for our meal?
I apologize for not being more on the ball with this update; this conference has been a bit overwhelming.
Anyhow, there’s been a lot of talk here about the growing (?) sustainable seafood movement in Japan, the world’s #1 seafood consumer per capita. The Marine Stewardship Council (MSC) is claiming that there’s a burgeoning awareness within the Japanese consumer public: In 2004, there were no MSC-certified products available in Japan. Today, there are 150.
While I’m certainly glad to see that more and more fisheries are being certified by the MSC, I don’t necessarily agree with their conclusion. The MSC-certified products available in Japan are largely imports from fisheries that also sell their product to other countries, especially in Europe and North America, where the public is much more aware of the MSC. Commitments like those made by WalMart (all wild seafood to be MSC-certified by 2014), or the entire country of Holland (only MSC-certified wild fish to be sold) help to drive demand in these areas.
One could argue that Japan is importing the same products they had been five years ago, but the products simply happen to be MSC-certified now and weren’t previously. So is this really indicative of a growing awareness in Japan?
As of March 2008, a study undertaken by the Japan office of the MSC indicated that only 8% of the surveyed public were aware of the MSC label. That number decreases to 5% when the survey is narrowed to pregnant women and mothers (a demographic which is often responsible for shopping for food and domestic goods, including fish).
The story becomes even more telling when you start to look at the actual products coming from Japan that are being certified by the MSC: Products like snow crab and skipjack tuna. These are items that have garnered popularity beyond Japan with the expansion of the sushi industry into a global phenomenon. Compare this to those fish that were “left behind,” as it were — fish like sayori and kohadathat are only rarely encountered in other countries but have immense popularity and cultural value in Japan.
One could imagine that if awareness of and value for MSC certification was growing among the Japanese public to a level where it was driving demand, we would be seeing certification efforts on these domestically-driven fisheries as well. And yet…?
